" ATTORNEY Patented Feb. 7, 1933 UNITED STATES PATENT OFFICE HARRY H. EVANS, OF NEW YORK, N. Y., ASSIGNOR TO ADJUSTA COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK BUCKLE SETTING DEVICE Application filed April 29, 1931. Serial ltd-533,713.

This invention relates to a set for setting the prongs of prong-attached buckles and the like; and the immediate object thereof is to provide a simple and efficient tool for setting 5. the prongs of hook buckles, and of staples therefor, by which they are to be attached to belts, bands, etc-for example, to the waistbands of trousers and to the waistand/or leg-bands of knickerbockers.

To this end, my new setting device comprises, briefly stated, a seating member, preferably the lower member of the set, which receives and positions the buckle with its prongs and usually an end hook-piece projecting upwardly; and, cooperating therewith, a setting member provided on its opposite sides with anvil elements adapted to engage the points of the one or more prongs on each side of .the buckle and to first turn them outwardly and then force them around in a loop and back to the body of the buckle, and, preferably also, at its rear end with a head adapted to set the hook-piece. In its preferred form, the upper member is further provided at its forward end with means for releasably holding a staple in position with its prongs downwardly extended, and the lower member carries a cooperating anvil element adapted to engage the points of the two prongs at each end of the staple and turning them inwardly towards each other, to set them. These two members are to be mounted in the usual or in any suitable manner, the upper setting member preferably as the movable member, in a hand, foot, or motor operated press.

One practical embodiment of the invention is shown, by way of illustration and not of limitation, in the accompanying drawing, in which v Figure 1 is a perspective view of the device, showing the upper member in raised position and partly in section and a buckle in p osit.ion on the lower member; Fig. 2 is a view showing in perspective the lower face of the upper member; Fig. 3 is a cross-sectional view of the two members and of a buckle and a band to which the buckle is to be attached Fig. 4 is a perspective view of the end of a band to which a buckle has been attached; Fig. 5 is a view, similar to Fig. 1, showing the forwardends of the two members and a buckle staple positioned thereon; and Fig. 6. is a perspective view of the end of a band and of the attached staple.

Referring to the drawing, the lower seatingmember 10, which as usual is to be set into and secured in the bed of a setting'machine, has an upper face with slightly raised sides which extend from its rear end forwardly for a portion of its length and provide opposite- 0.1 ly disposed shoulders ll 11, and, in the preferred form shown, uponthese raised sides are secured narrow plates 12 12 which project inwardly slightly beyond the shoulders to form shallow grooves suitably spaced apart to receive and guide the side edges ofv the buckles; and to the rear end of the member is secured an upwardly projecting stop 13. This member, as here shown, also has in its upper face a shallow depression let, convexly. curved in section, which extendstransversely thereof near its forward end and constitutes an anvil element for setting the prongs of buckle staples. v

The upper setting member 15, provided with a suitable shank by which it is secured to the movable plunger of the setting machine,'as usual, has in its lower face a central longitudinal recess16 and two oppositely" disposed shallow grooves '17 17, each with a gently -inclined inner and asteeply-inclined outer wall joined at the bottom by a slight concave curve, which extend from the rear end of the. member forwardly for a portion of its length and constitute. anvil elements for setting the prongs of the buckles. The member is also equipped, for setting the hooks of the buckles, with a setting head 18 which is adjustably mounted, within a recessed'chamber 19 at the rear end of the member, by means of a threaded shank 20 passing through a threaded opening 21 .and locked in adjusted position therein bya lock-nut 22. The sides of the recess 16 are cut away at 23 23,, at the forward ends of the, anvil elements, and again, in the narrower forward end of the member. to formshallow flat botto-med notches 2 1 24 adapted to receive a staple, and, within the recess, there is mounted a spring-finger 25 which extends forwardly 0.0,.

therein and somewhat beyond the end of the member.

For the buckle setting operation of the device, a buckle a, with integral prongs b b and an end hook-piece 0 stamped therein and bent up at the back thereof and preferably after the buckle has been positioned upon and its prongs pressed through the end of a band a; or other article to which it is to be attached, is placed face down on the'seating member, and, its side edges entering and sliding in the guide grooves, is pushed back therein until its end, or the hook-piece at its end, abuts against the stop 13; and, when thuspositioned and held and the setting member is forced downwardly, the gently-inclined inner walls of'the anvil elements engage the tips of' the prongs on the opposite sides of the buckle and press them outwardly and then the tips are looped over against the steep outer walls and forced down and back through the band, as shown in dotted lines in Fig. 3, thus fastening the buckles securely and permanently to the band. At the same time and by the same operation the head 18, suitablyadjusted for the thickness of the band to which the buckle is attached, engages the tip of the slightly inclined hookpiece of the buckle and sets it down to form the hook at the back of the band.

To set'the buckle staples, a staple d, with its four'prongs e e projecting downwardly, is placed midway its length upon the extended end ofthe finger 25 and is pressed down on and then back along the finger to position'to enter the notches 24 24 into which it is raised and there held by the finger; the end of the strap y to which it is to be attached, usually the other end of the same strap to which the buckle'has been attached, is then positioned over the transverse anvil element of the seating member; and then, as the machine is operated and the upper member is forced downwardly, the prongs of the staple 1 are forced through the band and are set therein, the two prongs at each end of the staple being set towards each other as shown in dotted lines in Fig. 6'.

His to be understood that certain features of the device may be used without others and that the structural details thereof may be modified, within the scope of the appended claim, without departing from the spirit or sacrificing the substantial advantages of the invention.

What I claim as new and desire to secure by Letters Patent, is

A buckle setting device comprising, in combination, a seating member having oppositely disposed guide elements adapted to engage the sides of and to position laterally a pronged buckle with an upwardly projecting hookpiece, a stop adapted to engage the end ofand to position the buckle longitudinally, and, cooperating with the said memto form the hook.
